针对DGL400型冷再生机在施工过程中出现的因弹性联轴器损坏而无法工作的故障,通过拆检、分析发现,弹性联轴器径向紧定螺钉提供的的拧紧力矩不够,导致弹性联轴器轴套和液压泵花键轴因轴向摩擦力不够而产生轴向相互移动,致使轴套端面和液压泵止口法兰触碰,是造成弹性联轴器轴套端面发蓝和花键破损的主要原因。根据故障原因,给出加深轴套夹紧缝深度等解决措施。经实践检验,解决措施可行。
Aiming at the failure of DGL400 type cold regenerator which can not work due to the damage of the flexible coupling during the construction process, it is found through disassembly and analysis that the tightening torque provided by the radial set screw of the flexible coupling is not enough, Axle sleeve and hydraulic pump spline shaft due to insufficient axial friction due to axial mutual movement, resulting in sleeve end face and pump flange flange touch, is caused by flexible coupling sleeve end bluish and flowers The main reason for broken keys. According to the cause of the failure, give the solution to deepen the depth of the clamping sleeve of the sleeve. After practice test, the solution is feasible.
